You are right -- in no way is xs:boolean different -- now. But if the Data Model were saying that 0 and 1 are not simply "string representations" (note that I didn't use '0' and '1' in my previous example but just 0 and 1 -- that is not the strins '0' and '1') but that 0 and 1 are *the* two xs:boolean constants, then it would make difference as the result of evaluating a boolean expression would be not a "representation" but a real (or native, or genuine) boolean value. Isn't it natural for a type to have its own genuine values and not only a "representation"? ===== Cheers, Dimitre Novatchev. http://fxsl.sourceforge.net/ -- the home of FXSL __________________________________ Do you Yahoo!?
